You have to remember that traffic officers don't tend to have an imagination.
They have their traffic regulations handbook and that is their bible.
They're not called snakes or black rats for nothing.
If I was to pull someone with what appeared to be fogs on I would obviously as a keen modder be able to make a reasonably informed decision, whereas the rats would see black and white- no grey area.
Well yeah ... but misinformed coppers are no reason to avoid making a modification. At the end of the day, if they wrongfully issue tickets or order for something to be removed, there is surely an appeals process that will fall down on the side of the person who has their facts and figures right, rather than the person with white hat?
